To all whom, it may concern..-

Be it known that I, SHERMAN T. WALP, a citizen of the United States, residing at Summerford, in the county of Madison and State of Ohio, have invented a new and useful Screen- Frame, of which the following is a specification.

This invention relates to frames for windowscreens and similar structures, and has for its object to provide a simply-constructed and easily applied and operated device which may be quickly inserted into and removed from a window-frame and which when locked in position will beremovable only from the inside of said window-frame.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification and in which corresponding parts are denoted by like designat-' ing characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape,- proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages.

In the drawings, Figure l is a transverse section on the line 1 1 of Fig. 2. Fig. 2 is an elevation of a portion of a window-frame and one of the sashes with the improved screenframe in position in the window-frame.

The screen-frame, which is represented at 10, may be of any required size and is preferably formed with one of the side members divided longitudinally, the divided portion 11 being connected to the adjacent stationary side member by hinges 12 13, so that it will swing in only onedirection upon said stationary side member. provided with a stop-plate 14, extending laterally from its hinged side, and the adjacent stationary side member provided with a looking member 15, having a longitudinal slot 16, through which clamp-screws 17 18 are inserted into the screen-frame to provide for the vertical movement of the locking member. The

locking plate or member is also provided with a lateral projection 19 for bearing against the stop-plate 14 when said locking-plate is in one position and releasable therefrom when the The divided portion 11 is locking-plate is in its other position. By this means when the projection 19 is in position bearing against the stop-plate, as shown in full lines in Figs. 1 and 2, the divided portion 11 will be rigidly supported in transverse alinement with the remainder of the screenframe; but when the position of the lockingplate is reversed, as indicated by dotted lines in Fig. 2, the divided portion may be turned. at an angle to the remainder of the screenframe, as indicated bydotted lines in Fig. 1.

The screen-frame, together with its divided portion 11, will just fit in between the sides 21 of the window-frame, preferably beneath the upper sash, a portion of which is indicated at 22, with the sash member bearing upon the screen-frame and its divided portion, while the latter rests upon the window-sill, (represented. at 23.)

When the screen-frame is to be inserted, the locking member 15 is moved upward to release the stop 14 and permit the hinged member 11 to be folded toward the body of the frame, and thus reduce the width of the frame, so that said frame will pass the parting-stop 24 and be positioned beneath the upper sash and outside the path of the lower sash. The divided portion 11 is then replaced in position in transverse alinement with the remainder of the screen-frame and the locking-plate permitted to drop into position, with its projection 19 bearing against the stopplate 14, which firmly locks the screen-frame in place and prevents its removal until the locking-plate is released. The locking-plate ments of the same.

It will thus be noted that a simply-constructed and easily applied and operated device is produced which will effectually protect the building to which they are applied from flies, mosquitoes, and other insects, and

one which cannot be removed from the outside.

Having thus described the invention, what is claimed is- 1. A screen having one of its side members divided longitudinally and hinged together, a

stop-plate extending laterally from the hinged side of said divided portion, and a verticallyadjustable member secured to said frame and adaptedto engage the stop-plate for locking said divided portion in transverse alinement with the adjacent side member of the screenframe.

2. A screen-frame having one of its side members divided longitudinally and hinged together, a stop-plate extending laterally from the hinged side of said divided portion, and a vertically-adjustable locking member secured to the frame and provided with a lateral projection adapted to engage the stop-plate for locking said divided portion in transverse alinement with the adjacent side member of the screen-frame.

3. A screen-frame having one of its side Witnesses CHAS. BoIsoL, IARY JoNEs.
